Unconventional Gas Exploration
Who should attend?
Geologists, explorationists and reservoir engineers who want to improve their knowledge of Unconventional Gas exploration.
The three major forms of unconventional gas include shale gas, coal bed methane (CBM) and tight gas. All have become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential unconventional gas reservoirs in Canada, Europe, Asia, and Australia. The course reviews the fundamental principles of unconventional gas formation, development of exploration models and approaches to quantitative assessment using geochemical and geological data. Some additional comment will be included on the prospectivity of liquids in unconventional reservoirs ('shale oil').
This course will cover the following topics:
- Fundamentals of fluid behaviour in low permeability rocks
- What are Shale Gas, CBM, tight gas?
Petroleum system fundamentals
- Hydrocarbon source rock characterization
- Source richness, quality and maturity
- Shale Gas generation: process and habitat
- Shale Gas systems and classifications
- CBM generation process and habitatCBM systems and classifications
- Tight gas generation process and habitat
- Tight gas systems and classifications
- Definition of workflows
- Application of geochemistry in unconventional gas assessment
- Sample analytical techniques
- Overview of petrophysical techniques
- Overview of drilling and completion practice
- Production characteristics of unconventional gas reservoirs
- Sample analytical techniques >
- Commercial considerations
The course will include a staged exercise of unconventional gas assessment in the Western Canada Sedimentary Basin, examining regional models, definition of unconventional play fairways and a quantitative assessment of prospectivity.
